This invention relates to anchors for fasteningfbucks` and the like into place, and with regard to certain more specific features to means for permanently holding objects to concrete and like surfaces.

Among the several objects of the invention may be noted the provision of means'y adapte-d to be readily fastened to the object to be held, the provision of means for driving a nail or the like therethrough into concrete or other hard and brittle material without loosing a grip or hold because of chipping away of said material, the provision of a compact and simple device which may be shipped flat, and one which is exceedingly easy to manu- Other objects will hereinafter. Y

The 'invention accordingly comprisesthe elements and combination of'elements, features of construction, and arrangements of parts which will be exemplified in the struclirereinafter described, and the scope lof the applicationof which will be indicated in the following claims.

In the accompanying drawings in which are illustratedtvvo of various possible embodiments of the invention,

at the apex thereof and a hollow portion thereunder. The portion 1 is crimped laterally 'along a line 7, on'the outside of which is formed a tongue or fastener 9. Y y

The piece thus far deseribedycomprises a stamping, properly cut, formed and crimped, all of which operations may be completed at a single operation of a die. Fig. 7 indicates that the :under side'of the conical portion 3 forms a hollow or depression 10 to be usedl for purposes hereinafter 1 to be described.

' The cone 3 is formed and' drawn from material which previously of thvesheet l.y p

, Fig. ll, which'. shows the tongue flat, illustrates the preferred shipping vform of the' device, althoughl it may be shipped'in the formed a flat portion form illustrated in Fig-2.I In Fig. '2 the tongue 9 has been turned upwardly at an angle of approximately ninetyV degrees .to

Laien? the portion l. vThis bending may hel done during the process of manufacture,'if desired, or by means of a hammerblow or the;

likev at the time that the anchor is `pu't'int'ov use. rFhe material comprising the anchor is of sufficient thickness to provide ample stiffness to the cone 3 andthe benttongue 9, and it may be made proof vagainst corrosion by choosing the proper material or coating the material such as by performing atinning, galvanizing or the like operation thereon. 1

InFig. 6 is illustrated a modified form of tongue 9 having a plurality of tines 11. Two tines 11 are illustrated in Fig. 6, but their number may be increased indefinitely. The modified anchor B' shown in` Fig.'v 6 ismanufactured in a manner analogous .to theway in which the previously described'form A is manufactured. f Y The application'of 3l and 1l. Each wooden leg 13 of the buck'is n theanchors for` holding a door buckm place is illustrated `in` Figs.

One or Y Vth the present invention, the iirst chips engendered are retainedin the recess 9 insteadoffiying away and as the nail is further driven are packed into said recess .there-A by preventing-` further chipping. As the linal blows are given Vto seat the headon y thecone 3, the cone is somewhat, though not Vcompletely 4flattened, and the chipped materialv therebeneathis ,tightlyl compressed.

The; result isV an improvedl holdingV power with the present anchor. `The hardened nail :serves the :purpose of piercing the hard loormaterial Withouthending. The open- .Qing` 5 ismade slight-ly smallerthan the nail so thatasxthe nailisdriven it is frictionally prevented yfrom.rebounding from the hard surface.' The conical portion-` also supportsV the nail Whileiit isk being driven so that it. neednotbeV manually held. Increased safety` is thus provided for the-fingers of an operator. I Y l Itistobe understood that, if desired, the bucks orjthelike: may be` applied ,to Wooden v` or other relatively ,softl lfloors.V A hardened orv other nail` may be, used. This anchor also providesan improved result when thev floor orthe Ylike isnot hard and apt to chip, because aside fromthe anchors chip-retain-y ing qualit-ies, the strained conical portionv 'actsasa compression brace. after nailing.

The

Y After the strips-21am laid afiller 23 ifs strips. r1`he carpet 25 is laid over the filler v23 and strips 21, and held to the latter byv quarter-round pieces 27 or the like.

Beforelaying the carpetV and quartenround strips 27, the Wall W of the room is usually surfaced with plaster l). Just before plastering is done, a ground strip29 should `be applied'at the upper portion of the wall W7 Vfor fastening picture molding and the like. This ground strip 29 may be fastened to the wall by means of the present improved anchor.V Anchors are driven into the back ofthe groundl strip 29v=before it is applied. These anchors preferablyV pro.

trude their conical portions from each side ofthe strip, that is, if the strip doesnot y abut the ceiling. y In finishing a roomv theV carpet lstrip and ground strip; are usually laidI at the same time. Plastering is then accomplished. It may be seen that this present type of anchor may-.be effectively used for various attachment* purposes in and about building yto `have fastenings made therewith,` iMuch time iseconomized, because heretofore itwas: necessary todrillv holes foi-applying expand ing holders for each fastening to be made vconstructionwherehard or soft surfaces are in hard material. Vvith the Vpresent invention a multiplicity yof'operationsare conif densed into a few. l Better alignment maybe accomplished because-.no1 drilledholes need be met byva plurality ofl fasteners.

In View of theabove, it `Will`bes`een that the several Y' objects of the` invention are achieved Iland othery advantageous results attained.

As many changes could be made in carrying out the; above constructions without departing from the scope-of the 1nvent1on1t 1s intendedth'at all matter contained inthe y above description or shown in theaccompanying drawings shall be interpretedy as illustrative and not in a limiting'sense. .s
